Detailed Description

In order that those skilled in the art will better understand the present invention, a detailed description of the same will be given below with reference to the accompanying drawings in this embodiment, and it is apparent that the described embodiment is only a partial embodiment of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.

Fig. 1 is a schematic flow chart of a draining method of a drying apparatus according to the present invention, where the method may be performed by a draining device of the drying apparatus, the draining device of the drying apparatus may be implemented in hardware and/or software, and the draining device of the drying apparatus may be configured in the drying apparatus.

The drying equipment provided by the embodiment comprises a drainage device, wherein a metal component is arranged in the drainage device.

The water draining device is used for draining water generated by the drying equipment in the drying process of clothes, and is arranged at the bottom of the drying equipment so that the water is drained outwards. The drainage device provided in this embodiment may be implemented by a drainage pump.

The metal components can be realized by metal strips, and the number of the metal components is generally 2, so that a conducting circuit is formed by two metal components, and the resistance value of the metal components in the conducting circuit can be measured.

Generally, when the water amount in the drainage device is larger, the resistance of the metal component is smaller, and conversely, the resistance of the metal component is larger. Illustratively, the resistance of the metal component may be tens of ohms, thousands of ohms, or the like depending on the moisture content. When the drainage device has no moisture, the resistance of the metal component is measured as an air resistance, and the air resistance is generally large enough, i.e. the maximum resistance (for example, several kiloohms). The specific resistance of the metal component obtained is not limited herein, and is based on actual measurement.

Specifically, referring to fig. 1, the drainage method of the drying apparatus provided in the present embodiment may include the steps of:

s110, acquiring the current resistance value of the metal component when the drying program runs to the current time period.

Generally, different drying procedures correspond to different total drying durations, and illustratively, the drying procedures may be: quick drying, mixed drying, four-piece set drying, wool drying and the like. The corresponding total drying duration may be: 30 minutes, 60 minutes, 120 minutes, 150 minutes, etc.

It is known that, as the drying program runs, the moisture dried from the clothes by the drying device is reduced, and on the premise of timely discharging the moisture in the drying device, the water discharging device needs to be prevented from being started excessively frequently, and the drying program can be divided into a plurality of time periods in time intervals, so that the current resistance value of the metal component is obtained once when the drying program is executed to the current time period. When the drying process is divided at time intervals, the current resistance value of the metal component can be obtained once in preset time periods at intervals, the current preset time periods can be 10 minutes, 15 minutes or 30 minutes, and the like, and the specific preset time interval values are not limited herein.

Because the water baked from the clothes to be dried is in a decreasing trend along with the running of the drying program, different time intervals can be set for the same drying program to divide the drying program into a plurality of drying stages according to the running time in order to further reduce the starting times of the water draining device. For example, the drying process having a total duration of 60 minutes may be divided into three drying stages (0, 10), (10, 30) and (30, 60), i.e., the resistance values of the corresponding metal components are obtained when the process is run to 10 minutes, 30 minutes and 60 minutes, respectively.

Optionally, the same time interval may be selected for each drying program of the drying apparatus, for example, the drying stage may be divided into (0, 10), (10, 30) for quick drying (30 minutes) with the shortest drying time, for example, mixed drying (60 minutes) for example, which includes (30, 60) drying stages based on the quick drying divided drying stages, and four sets of drying (120 minutes) for example, which includes (60, 120) drying stages based on the mixed drying.

S120, determining the current water level height of the drainage device according to the current resistance value.

Before programming, a developer can test the resistance corresponding to different water level heights possibly eliminated by the drying equipment in a test environment to obtain a mapping relation table of the resistance corresponding to different water level heights in the drying process of the drying equipment, wherein one water level height in the current mapping relation table corresponds to one component resistance.

Because the water quantity discharged by the drying equipment is influenced by the material of clothes, the temperature of the drying program and the total duration of the drying program, when the drying program runs to the current time period, the current resistance value of the metal component corresponds to various conditions, and correspondingly, the water level height corresponding to the current resistance value also comprises various conditions. In order to reduce the data amount in the standard mapping relation table, the water level height corresponding to the resistance value in a range can be averaged, and the mapping relation table corresponding to one water level height in one resistance value interval can be obtained.

When the current resistance of the metal component in the current time period is obtained in step S110, accordingly, the current water level height in the drainage device can be obtained in the mapping relation table, so as to determine how much water is probably present.

S130, determining the current drainage time length of the drainage device according to the current water level height and the current running time length of the drying program, and controlling the drainage device to drain the drying equipment according to the current drainage time length.

The working time for starting the water draining device to drain is influenced by the current water level height and the current running time of the drying program, wherein the current running time can be the time of the drying stage of the current program. This step can be understood as follows:

when the drying program runs to a first drying stage (for example, 10 minutes), the water content obtained by the water draining device is large, for example, the water level height is 5 cm, and when the drying program runs for 10 minutes, the water draining device is controlled to start to drain, and the current water draining time length corresponding to the first stage can be 60 seconds; however, during the process of the drying procedure to the second stage (for example, 11-30 minutes), wherein during the process of 11-12 minutes, the drying device is drying the clothes to generate a certain amount of water, and the draining device is draining the drying device, so that during the process of starting the draining device to drain water, the water generated during the initial process of the second stage is considered, and the draining time corresponding to the first stage is long.

Further, when the drying program is operated to the third stage (for example, 31-60 minutes), it is detected that the water level generated in the second stage may be 5 cm, and since the water content of the laundry to be dried is gradually reduced, the current water level generated in the first stage is the same as the current water level generated in the first stage in that the time interval of the second stage is longer than that of the first stage, and thus, the water generated at the start of the third stage is not more than that generated at the start of the second stage, and the current drainage period corresponding to the second stage may be shorter than that of the first stage, for example, may be 45 seconds.

The device is arranged in such a way, the drainage device can also work for different time according to the difference of the current drying time period of the drying program under the premise of draining the water in the drying equipment, so that the loss of related hardware in the drainage device is reduced, and the service life of the drainage device is prolonged.

In a preferred embodiment, in the drainage method of the drying apparatus according to the embodiment of the present invention, during the operation of the drying program, the current drainage time length of the drainage device is in a functional relationship with the current operation time length and the current water level height of the drying program.

The current functional relationship may be a linear function, that is, in the current operation time period, the current drainage time length of the drainage device is in a functional relationship with the current operation time length and the current water level height of the drying program.

In addition, in each drying stage, even though the water levels corresponding to different stages are the same, the drainage time length of the equipment in different stages is also different, so that it can be understood that the whole drying program comprises a plurality of stage functions, and each stage function is different along with the difference of the drying stage where the current running time is, and the corresponding function slope is also different. I.e. the function slope of the corresponding stage gradually decreases with increasing operation duration, i.e. the function slope of the first stage is the largest and the function slope of the last stage is the smallest.

The drainage scheme of the drying equipment provided by the embodiment comprises the steps of firstly obtaining the current resistance value of a metal component when a drying program runs to the current time period, and then determining the current water level height of a drainage device according to the current resistance value; and finally, determining the current drainage time length of the drainage device according to the current water level height and the current running time length of the drying program, and controlling the drainage device to drain the drying equipment according to the current drainage time length. According to the technical scheme provided by the embodiment, the metal component is arranged in the drainage device of the drying equipment, the resistance of the metal component is obtained, so that the drainage duration of the drainage device is determined according to the current resistance, and the water quantity in the drainage device is related to the drainage duration of the drainage device, so that the problems of repeated starting of the drainage device and shortening of the service life of the drainage device in the existing scheme are solved, the working mode of the drainage device is optimized, and the drainage cost is saved.

Fig. 2 is another flow chart of the drainage method of the drying apparatus according to the present invention, and the relationship between the present embodiment and the above embodiment further refines the corresponding features of the above embodiment. As shown in fig. 2, the method may include the steps of:

s210, acquiring the current resistance value of the metal component when the drying program runs to the current time period.

S220, determining a target resistance interval from the mapping relation table according to the current resistance.

The mapping relation table comprises a plurality of resistance value intervals, and the advantage of the method is that sample data in the mapping relation table can be reduced, so that the target resistance value interval can be determined from the mapping relation table more quickly according to the current resistance value.

Wherein, a resistance interval corresponds to a water level. The current water level height may be an average value of water level heights corresponding to resistance values that may occur in the current resistance value interval.

In setting the resistance interval, a resistance value in which the water level difference is a certain value may be set as an interval, and for example, the current water level difference may be 0.5 cm or 1 cm, etc., and the value of the specific water level difference is selected without limitation.

S221, determining the current water level height according to the target resistance interval.

And acquiring a corresponding water level height in the mapping relation table according to the target resistance interval, wherein the current water level height is the water level height corresponding to the current resistance of the metal component when the drying program runs to the current time period.

S230, determining the current drainage time length of the drainage device according to the current water level height and the current running time length of the drying program, and controlling the drainage device to drain the drying equipment according to the current drainage time length.

The current running time length can be the time length of the current program running in the drying stage, and the current draining time length is determined for the draining device according to the time length of the current drying stage and the corresponding water level height.

Because in step S220, a resistance interval corresponds to a water level, the current water level may be an average value of the current resistance interval, and if the current water level is less than the actual water level corresponding to the current resistance, the drainage method provided in this embodiment includes a default drainage duration, for example, may be 5 seconds, that is, the default drainage duration is additionally run on the basis of determining the current drainage duration of the drainage device according to the current water level and the current running duration of the drying procedure, so as to prevent the water from not being drained cleanly.

S240, acquiring the last resistance value of the metal component when the drying program runs in the last time period.

When the drying program runs to a drying stage corresponding to a non-first time period, the other stages can execute the current step so as to detect the water discharged by the drying equipment according to the resistance change conditions of the current time period and the previous time period, and determine whether the clothes are rinsed cleanly or not.

S241, determining the previous water level height of the drainage device according to the previous resistance value.

The manner of determining the previous water level in the current step is the same as the manner of determining the current water level in step S221, and will not be described here.

S242, determining the water quality in the drainage device according to the current water level height, the previous water level height, the current resistance and the previous resistance.

In a preferred manner, the drainage method of the drying apparatus provided in this embodiment determines the water quality in the drainage device according to the current water level height, the previous water level height, the current resistance value and the previous resistance value, including the following manners:

determining the actual resistance change of the adjacent time period according to the previous resistance and the current resistance; determining standard resistance variable quantity of adjacent time periods according to the previous water level height and the current water level height; and when the difference value between the actual resistance change amount and the standard resistance change amount exceeds the preset range and the actual resistance change amount is smaller than the standard resistance change amount, determining that the water quality in the drainage device is poor.

If the clothes are rinsed cleanly in the washing process, under the standard state, the resistance of the obtained metal component gradually increases along with the reduction of moisture, and the resistance can be in a larger change relation along with the change of the water level, such as hundreds of ohms; if the water is not rinsed, the water contains more conductive ions, and the obtained actual resistance value has small variation, for example, only varies by a few ohms or tens of ohms.

And when the difference between the actual resistance change and the standard resistance change is larger, namely the difference exceeds a preset range, determining that the water quality in the water discharge device is poor, and indicating that the clothes are not rinsed cleanly.

The current preset range may be that the actual resistance change amount fluctuates within a certain range of the standard resistance change amount value, for example, the difference cannot be greater than 50 ohms, etc., and the specific preset range is not limited herein.

On the basis of the above preferred embodiments, in this embodiment, when it is determined that the water quality of the laundry is cross-linked and not rinsed, a preset program may be executed in the next time period to optimize the water quality in the drainage device, where the preset program includes a deodorizing program, and/or a water spraying program.

The deodorizing procedure can prevent the peculiar smell generated by the fact that the clothes are not rinsed, and the water spraying procedure is used for spraying certain moisture to the clothes so as to achieve the effect of diluting the foam in the clothes. Stopping executing the preset program and continuing executing the drying program until the obtained difference value between the actual resistance change amount and the standard resistance change amount is within the preset range. The preset program with default duration can also be added in the drying program to play a role in relieving, and the degree of optimizing the water quality in the drainage device by specifically adding the preset program is not performed first.

In an alternative case, the rinsing degree of the clothes is poor, the condition that the clothes are required to be diluted by a large amount of water is possible, the clothes can be correspondingly selected according to actual conditions, when the rinsing degree of the clothes is poor, feedback can be given to a user to prompt whether the clothes are rinsed again in the washing equipment, and if the user selects 'yes', the current drying program is ended; if the user selects no, a deodorizing program with a default duration can be added in the drying process, and/or after the water spraying program, the corresponding drying program is continuously executed.

Optionally, when detecting that the water quality of the clothes is poor and a large amount of water is needed for dilution, a large amount of water can be sprayed out by the drying equipment, the water content of the clothes can be correspondingly increased, and the corresponding drying program can be re-executed. The solution of poor rinsing degree of laundry is not particularly limited here.

S250, when the current resistance value of the metal component is equal to a preset value, controlling the drainage device to stop working after a default working time.

The current preset value is the detected air resistance value of the metal component, at the moment, the fact that the water in the drainage device is discharged completely can be determined, and further, in order to prevent the fact that the influence of a small amount of water in the drying equipment on the resistance value is small, the drainage device is controlled to stop working after a working default time length, and the current default time length can be 5 seconds or 10 seconds and the like.

The specific air resistance value is not limited herein, and the values obtained by the developer under the specific experimental environment are the same; the values of the corresponding default durations are also not limited by the above examples.

According to the drainage scheme of the drying equipment, the metal component is arranged in the drainage device, the water quantity generated in the drying process of the clothes by the drying equipment can be obtained according to the resistance value of the metal component, the corresponding drainage time length is determined for the drainage device by combining the current running time length of the drying program, the water quantity generated in the drying equipment is associated with the drainage time length of the drainage device, the working mode of the drainage device is more reasonable, on the basis of saving the drainage cost, the water quality of the drainage device can be detected by obtaining the resistance value of the metal component, whether the clothes are rinsed cleanly in a washing stage is determined, and when the clothes are not rinsed cleanly, the working mode of the drying equipment is diversified by adding the deodorizing program and/or the water spraying program, and user experience is improved.
